Note
Random sampling creation ops are listed under :ref:`random-sampling` and include: :func:`torch.rand` :func:`torch.rand_like` :func:`torch.randn` :func:`torch.randn_like` :func:`torch.randint` :func:`torch.randint_like` :func:`torch.randperm` You may also use :func:`torch.empty` with the :ref:`inplace-random-sampling` methods to create :class:`torch.Tensor` s with values sampled from a broader range of distributions.

There are a few more in-place random sampling functions defined on Tensors as well. Click through to refer to their documentation:
- :func:`torch.Tensor.bernoulli_` - in-place version of :func:`torch.bernoulli`
- :func:`torch.Tensor.cauchy_` - numbers drawn from the Cauchy distribution
- :func:`torch.Tensor.exponential_` - numbers drawn from the exponential distribution
- :func:`torch.Tensor.geometric_` - elements drawn from the geometric distribution
- :func:`torch.Tensor.log_normal_` - samples from the log-normal distribution
- :func:`torch.Tensor.normal_` - in-place version of :func:`torch.normal`
- :func:`torch.Tensor.random_` - numbers sampled from the discrete uniform distribution
- :func:`torch.Tensor.uniform_` - numbers sampled from the continuous uniform distribution

The context managers :func:`torch.no_grad`, :func:`torch.enable_grad`, and
:func:`torch.set_grad_enabled` are helpful for locally disabling and enabling
gradient computation. See :ref:`locally-disable-grad` for more details on
their usage. These context managers are thread local, so they won't
work if you send work to another thread using the threading module, etc.
Examples:
>>> x = torch.zeros(1, requires_grad=True) >>> with torch.no_grad(): ... y = x * 2 >>> y.requires_grad False >>> is_train = False >>> with torch.set_grad_enabled(is_train): ... y = x * 2 >>> y.requires_grad False >>> torch.set_grad_enabled(True) # this can also be used as a function >>> y = x * 2 >>> y.requires_grad True >>> torch.set_grad_enabled(False) >>> y = x * 2 >>> y.requires_grad False
